NAME

6       cobblerd_selinux - Security Enhanced Linux Policy for the cobblerd pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  cobblerd  processes  via  flexible
11       mandatory access control.
12
13       The  cobblerd  processes  execute with the cobblerd_t SELinux type. You
14       can check if you have these processes running by executing the ps  com‐
15       mand with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep cobblerd_t
20
21
22

ENTRYPOINTS

24       The cobblerd_t SELinux type can be entered via the cobblerd_exec_t file
25       type.
26
27       The default entrypoint paths for the cobblerd_t domain are the  follow‐
28       ing:
29
30       /usr/bin/cobblerd
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       cobblerd policy is very flexible allowing users to setup their cobblerd
40       processes in as secure a method as possible.
41
42       The following process types are defined for cobblerd:
43
44       cobblerd_t
45
46       Note: semanage permissive -a cobblerd_t can be used to make the process
47       type  cobblerd_t permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

53       SELinux  policy  is  customizable based on least access required.  cob‐
54       blerd policy is extremely flexible and has several booleans that  allow
55       you  to manipulate the policy and run cobblerd with the tightest access
56       possible.
57
58
59
60       If you want to determine whether Cobbler can  connect  to  the  network
61       using  TCP,  you  must turn on the cobbler_can_network_connect boolean.
62       Disabled by default.
63
64       setsebool -P cobbler_can_network_connect 1
65
66
67
68       If you want to determine whether Cobbler can access cifs file  systems,
69       you must turn on the cobbler_use_cifs boolean. Disabled by default.
70
71       setsebool -P cobbler_use_cifs 1
72
73
74
75       If  you  want to determine whether Cobbler can access nfs file systems,
76       you must turn on the cobbler_use_nfs boolean. Disabled by default.
77
78       setsebool -P cobbler_use_nfs 1
79
80
81
82       If you want to allow users to resolve user passwd entries directly from
83       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
84       gin_nsswitch_use_ldap boolean. Disabled by default.
85
86       setsebool -P authlogin_nsswitch_use_ldap 1
87
88
89
90       If you want to allow all domains to execute in fips_mode, you must turn
91       on the fips_mode boolean. Enabled by default.
92
93       setsebool -P fips_mode 1
94
95
96
97       If  you  want  to allow confined applications to run with kerberos, you
98       must turn on the kerberos_enabled boolean. Enabled by default.
99
100       setsebool -P kerberos_enabled 1
101
102
103
104       If you want to allow system to run with  NIS,  you  must  turn  on  the
105       nis_enabled boolean. Disabled by default.
106
107       setsebool -P nis_enabled 1
108
109
110
111       If  you  want to allow confined applications to use nscd shared memory,
112       you must turn on the nscd_use_shm boolean. Enabled by default.
113
114       setsebool -P nscd_use_shm 1
115
116
117

PORT TYPES

119       SELinux defines port types to represent TCP and UDP ports.
120
121       You can see the types associated with a port  by  using  the  following
122       command:
123
124       semanage port -l
125
126
127       Policy  governs  the  access  confined  processes  have to these ports.
128       SELinux cobblerd policy is very flexible allowing users to setup  their
129       cobblerd processes in as secure a method as possible.
130
131       The following port types are defined for cobblerd:
132
133
134       cobbler_port_t
135
136
137
138       Default Defined Ports:
139                 tcp 25151
140

MANAGED FILES

142       The  SELinux  process type cobblerd_t can manage files labeled with the
143       following file types.  The paths listed are the default paths for these
144       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

284       SELinux requires files to have an extended attribute to define the file
285       type.
286
287       You can see the context of a file using the -Z option to ls
288
289       Policy governs the access  confined  processes  have  to  these  files.
290       SELinux  cobblerd policy is very flexible allowing users to setup their
291       cobblerd processes in as secure a method as possible.
292
293       The following file types are defined for cobblerd:
294
295
296
297       cobblerd_exec_t
298
299       - Set files with the cobblerd_exec_t type, if you want to transition an
300       executable to the cobblerd_t domain.
301
302
303
304       cobblerd_initrc_exec_t
305
306       -  Set files with the cobblerd_initrc_exec_t type, if you want to tran‐
307       sition an executable to the cobblerd_initrc_t domain.
308
309
310
311       Note: File context can be temporarily modified with the chcon  command.
312       If  you want to permanently change the file context you need to use the
313       semanage fcontext command.  This will modify the SELinux labeling data‐
314       base.  You will need to use restorecon to apply the labels.
315
316

SHARING FILES

318       If  you  want to share files with multiple domains (Apache, FTP, rsync,
319       Samba), you can set a file context of public_content_t and  public_con‐
320       tent_rw_t.   These  context  allow any of the above domains to read the
321       content.  If you want a particular domain to write to  the  public_con‐
322       tent_rw_t domain, you must set the appropriate boolean.
323
324       Allow  cobblerd  servers  to read the /var/cobblerd directory by adding
325       the public_content_t file type to the directory and  by  restoring  the
326       file type.
327
328       semanage fcontext -a -t public_content_t "/var/cobblerd(/.*)?"
329       restorecon -F -R -v /var/cobblerd
330
331       Allow  cobblerd  servers  to  read  and write /var/cobblerd/incoming by
332       adding the public_content_rw_t type to the directory and  by  restoring
333       the  file type.  You also need to turn on the cobblerd_anon_write bool‐
334       ean.
335
336       semanage  fcontext  -a  -t  public_content_rw_t   "/var/cobblerd/incom‐
337       ing(/.*)?"
338       restorecon -F -R -v /var/cobblerd/incoming
339       setsebool -P cobblerd_anon_write 1
340
341
342       If  you  want to determine whether Cobbler can modify public files used
343       for  public  file  transfer  services.,  you  must  turn  on  the  cob‐
344       bler_anon_write boolean.
345
346       setsebool -P cobbler_anon_write 1
347
348

COMMANDS

350       semanage  fcontext  can also be used to manipulate default file context
351       mappings.
352
353       semanage permissive can also be used to manipulate  whether  or  not  a
354       process type is permissive.
355
356       semanage  module can also be used to enable/disable/install/remove pol‐
357       icy modules.
358
359       semanage port can also be used to manipulate the port definitions
360
361       semanage boolean can also be used to manipulate the booleans
362
363
364       system-config-selinux is a GUI tool available to customize SELinux pol‐
365       icy settings.
